Typical results

In order to learn from the beergame, the data created by the players needs to be consolidated and plotted. Here, exemplary data of one beergame session is presented.

Bullwhip effect

The first figure shows the order distribution over 40 weeks and a typical bullwhip effect. It becomes obvious that the retailers reacted to the customer demand jump with a little time lag of two weeks.

Then the following stages all placed large orders, each of which magnified, thus creating a typical bullwhip effect.

Inventory fluctuation

The second figure shows the inventory fluctuation, with negative inventory representing back order.

Obviously, players move into back order. Having overreacted inventories then fill quickly in weeks 20-30.

Additional data

The third figure shows some additional game data. It shows the decrease in customer demand information upstream visualised by the average order amount by the four stages. More importantly, the increase in order fluctuation upstream is illustrated by the largest amount having been ordered in each stage and the number of small orders that were placed.

All this information is being used in the following debriefing session to discuss the bullwhip effect, its implications and the reasons for its existence.

Overview

This section provides an overview of the beergame, its history, rules, and different versions of the game. It also describes the bullwhip effect.

Please note that all explanations given in this section are based on the modified table version of the beergame, for which I also provide the materials in the respective section.
